be sent out continuously so data will be sent out continuously into the
air thus there is signal for user to tune their receiver.

Mode Setting：1 0
Slave testing mode for user to develop code for transmission：
Mode setting：1
Master testing mode for user to develop code for receiver：
on the slave side, RX LED(green)will be toggled once，in the mean time
slave will send back one frame of data, slave TX led( red) will be
toggled once. After having data received and verified, master will
toggle RX led(green) once. The same procedure will be repeated in the
next cycle again.
This is useful for software engineers to develop codes using this RF
module
